Looks to be on there right, but does your sprocket not have the mark to line up with the mount mark?
I thought they all did regardless of year, that's strange.
it does if you look down at the sproket the 1st tooth to touch it there the mark -

Ok I zoomed your pic and I can faintly see the line there I think...
Your pump isn't 180 out we know that for sure now. -

What timing marks are you referring to?
The "timing marks" to me are the mark in the pulley, the mark on the pump mount bracket, and the hole for the holder tool.
From the looks of your picture there, all of those are where they are supposed to be. -

If you go to the pulley and count back 3 or 4 teeth and look on the backside of said pulley is there a small notch on the edge of the pulley itself? This should be lining up with another small bar like protrusion on the top of the pump or another notch on the bracket that holds the pump in place.
Those are the marks I have on my 81. -

Your pump isn't 180 out we know that for sure now.
All we know is that externally the pump is in time. If the camplate was installed incorrectly then you need to set the pump up 180 out to get things timed correctly. -

To determine the IP is internally in-time, the engine can be turned and the Cyl #1 delivery valve should emit fuel at ~0o crank TDC.

Sorry I got your thread mixed up with another one. -

So I was reading through this thread more...
I'm getting fuel at all injectors I'm going to try and add pressure to the fuel tank and see what happens
One time you are saying fuel at all injectors...ok so ive made progress i found out that im not gettting fuel from the tank theres a block of some sort do i have a 2d pump? cause i saw this picture below and theirs wires running to it and
Then you say you aren't getting any fuel from the tank, and that the pump is sucking from the bottle fine...
the fuel lines from the tank go in to it then run up to the filter.
i also got a bottle and filled it with diesel and tried starting her with a bottle full of diesel no luck the pump is sucking from the bottle just fineyeah its weird tho she wont pump any more fuel when cranking its like it cant pull the fuel when air get in then she tires to fire its weird i can make a video to show you guys oh and the blue idk its diesel? the little screw it tight . i also removed the water separator
And the last update was the pump isn't even pumping fuel into itself anymore...
So what is it?
Are you stuck with a pump that won't pump?
Be 100% certain you have as much diesel as you can get into the pump...
However you gotta do it, fill the pump with diesel through both the in and out holes...easiest and fastest way to do this is buy a $19 primer bulb from WalMart and hook it up and pump it through like this:
While cranking you should have tons of fuel pumping through the pump going in and going out, regardless of the stop solenoid or anything else.
If the pump isn't pumping and circulating fuel on it's own, your vane pump inside the pump is faulty.
I could venture a scenario where the vane pump has just gotten a little varnished and gummed up over time, but was still limping along as long as it had a good steady stream of diesel still.
You ran it dry, got a bunch of air in there, maybe it sat around a while, and now the vanes are just simply stuck and the pump can't pump it's own fuel in.
I wish I had a nice high-res pic to show you the tolerances that are involved in that assembly.
Do you have the tools and know-how to swap a pump?

Looking at the picture provided by EcoTX I started to wonder if you have checked the voltage at the on off fuel valve itself on the back of the pump. Is that hanging up or not getting voltage? Or intermittent voltage from a loose connection. That would be even harder to find.

Getting voltage is only half the solution. You have to verify with a click and a look. They wear in strange places and yes the voltage is there but the plunger still does not come up to allow fuel in.
